Mexico City, Mexico Filed Apr. 24, 1961, Ser. No. 105,018 3 Claims. (Cl. 12S-16) This invention relates to a rotary vane-type internal combustion motor.

-It is the principal object of the present invention to provide a rotary vane-type internal combustion motor, in whichthe vanes plungers are movable in` and out of the rotor and. in which the supply of fuel is extended to the rear of the pistons to be` compressed by the plungers and forced into the spaces on the periphery of the rotor for delivery to the :combustion chamber under pressure.

Itis another object of the invention to provide a rotary vane-type internal combustion motor with sockets for containing the vane plungers so that they can readily adapt themselves to the interior face of the main housing to ensure against leakage between the spaces of the main Other objects of .the invention are to provide a rotary p vane-type internal vcombustion motor having the above objects in mind, which is of simple construction, inexpensive to manufacture, easy to assemble and keep in repair, has a minimum number of pants, compact, light in weight, etiicient and effective in use. t

:For a better understanding ofthe invention reference may be had to the following detailed description taken in i connection with the accompanying drawing, in which `FIGURE. 1 is an elevational view of the rotary vanetype internal combustion motor embodying .the features of the present invention with one half portion being broken away and shown in section,

FIG. 2 is a vertical sectional view of the internal combustion motor as` viewed generally on line 2--2 of FIG. 1, FIG. 3 is la vertical elevational view of the internal combustion motor, one of the end plates'having been ret moved to look in plan upon the interior of the main housing and upon the rotor, one half section looking upon ythe end of the rotor bearing lassembly carried by the end plate, and

t FIG. 4 is an end elevational view similar toFIG. 3 of the internal combustion motor with the end plate and the piston carrying rotor removed and looking in plan upon the inner face of the opposite end plate.

Referring now to the figures, 10 represents a main housing ring part having air cooling `fins 11 on its outer periphery andan internal circular wear'surface 12 on its inner periphery and providing a circular Work cham-y ber 13. Within the work chamber 13, there is a pistoncarrying rotor 14 that rotates about an axis indicated at 1,5fupwardly offset from the axtisof the chamber 13 in- Ilicated at :16 in an eccentric manner, VOn the opposite sides of the main housing ring 10 are motor and plates p `tric annular recesses 74 and 75 on one face and 77 and 3,101,076 Patented Aug. 20, 1963 ice The rotor 14 has a circular outer penipheral surface 26 against which a seal member 27 is pressed by a compression spring 28, both of which lie in a recess in the top of the main housing ring 10. This is to seal off at the top of the motor the combustion side of the chamber 13 from the intake side of the chamber.

On the intake or combustion side of the chamber 13 and in the inner periphery 12 of the marin housing 10 is an arcuate recess 29 extending clockwise as viewed in FIG. l from a transverse slot 31 in the periphery 12 for nearly a quarter turn to a point 32. In the respective end plates 17 and 18- are respectively side slot-s 33 and 34 also extending from the transverse slot 31 and that run coextensively with the recess 29 and taken therewith provide the explosion chamber in which the Ecarbureted mixture is released under pressure. A spark plug 36 is fixed within an opening 37 in the end plate 18 at the end of the transverse slot 31 in the main housing 10. The spark plug 10 is connected to an ignition coil not shown to ignite the gases delivered in the explosion chamber.

Disposed respectively in the respective end plates 17 and 1'8 are respective ball bearing assemblies 38 and 39 that support a rotor axle 41 having shoulders 42 and 43 against which the respective ball bearing assemblies ixed to hold the shaft against axial displacement from the rotor. vBall bearing retaining plates 44 and 46 are secured respectively by fastening screws 47 and 48 to the respective end plates 17 and 18 tothold the ball bearing assemblies in place.

Ring guides 51 and 52 are respectively disposed in respective ycircular recesses 53 and 54 and upon respective roller bearing assemblies 56 and 57 on reduced diameter portions 59 and 61 and held in place thereover and within the recesses by respective inner retaining plates 62 and 63 fastened to the end plates by any suitable means. Between the respective ring guides 51 and 52 and the outer periphery of the respective recesses 53 and 54,` there are provided pairs of pins 64 which carry vanes 66 and by these pins that project into the respective recesses from the respective sides of the rotor and the Vrecess being ec centric to the rotor axis willcausethe vanes 66 to move positively radially inwardly and outwardly in respective recesses 68 in adjustable sockets 69 and lying within sleeve 71 that are angularly adjustable in t cylindrical socket recesses to permit the outer end face of the vanes to adapt themselves to the periphery of the main housing ring 10 to provide a main ring housingtchamber.4 The rotor 14 is keyed to the shaft 41 by a key 73, FIG. l.

The side faces of the rotor are `provided with concen- 78 on the other face. These recesses 74 :and 75 carry respectively rotor oil rings 79 and 80 and 81 and 82.` These rings bear against the internal bearing retaining plates 62 and 63 and the respective end plates 17 and 18 to provide sealing engagement therewith and keep the oil against leakage toward the axle 41 and. the combustion chamber 13. The motor is supplied oil through holes 171 and 18 that are secured tothe main housing ring 10 t respectivelyby fastening bolts 19 and 21. These `endf` Hplates 17 `and 18V rspectivelyhave foot portions 22ja`nd p 23.jon .which the motoris'supported and` held upright On thev topj of the main housing, there is` extended a Vthe motor canr bevlifte'd and 92 in 'the rotor outer-surface 26. p

rThe rotor 14trotates clockwise and the vanes are workedginand.out` bythe pinstraversing the eccentric p `lannular 'recesses 53`|and` 54. After the combustion the product passeslnlthrough exhaust `portV 93 at the bottom A' of thehousing ning 10 tothe atmosphere. The fuel en` i Y pressure.

,v3 ters the vane recesses 8S from one side of the rotor and is forced by thel varies .to the other side of the rotor for discharge into the spaces `between vanes through the passage and whereupon itvis compressed into the pockets 92 of the outer periphery and inally released into the combustion space and exploded to effect the rotation of Y Y the rotor. These explosions take place in sequence causing steady rotation of the rotor. A safety valve 94 is provided in a hole 95 in the housing 1) to release excess The length of the explosion chamber is important as an vexplosion chamber should be kept well away from the entrance of the fresh gas mixture into the vane spaces and should there be a premature explosion, the safety valve 94 in the upper part of the motor will open. Suction,

compression, explosion and exhaust are accordingly effected in sequence to eiect the steady rotation` o f the `rotor.

While various changes may be Vmade in the detailed Y V table vane sockets operable in said socket recesses, radially adjustable vanes in said angularly adjustable vane sockets of the rotor having wiping contact with the inner usurface of the housing, slot means providedin the inner surface of the main housing and in the end plates at the opposite sides thereof to provide an explosion chamber within the housing surface, said cylindrical vaneV socket rotor having vane spaces in which the vanes are adjusted, passageway means in one-end plate for supplying gras mixture to fthe innery end of the vane spaces whereby" the gas mixture will be Vacted upon by the vanes, passageway meansin the opposite end plate for delivering the gas vane spaces to the opposite side of the rotor and to the housing removed from the explosion chamber, said rotorV having slots in its periphery into which the gaseous mixture from the main ringV housingchamber is compressed,
